I have the primal and the Raptor and love them.  Now looking for the Sigma tour!  A used one in very good condition.   A 15lb (but will consider 14lb also), about 3" pin,  single drill,  RH bowler with span of about 4 1/2 to 4 5/8 would do just fine.  Anyone willing to sell one please pm me your shipped price - NY zipcode 10029. thanks
